General Note
Welwyn Components reserves the right to make changes in product specification without notice or liability.
All information is subject to Welwyn’s own data and is considered accurate at time of going to print.
CONSTRUCTION
Cap and lead assemblies are fitted to a high purity ceramic
substrate. The resistive element is wound onto the
substrate and welded to the caps. The wound rod is then
moulded and fitted into an aluminium housing to give
optimum stability and reliability.
TERMINATIONS
Material
Solder dipped, copper clad steel wire.
Strength
The terminations meet the requirements of
IEC 68.2.21
Solderability
The terminations meet the requirements of
IEC 115-1, Clause 4.17.3.2
MARKING
The resistors are legend marked with type reference,
resistance value and tolerance. Values are marked in
accordance with IEC 62.
SOLVENT RESISTANCE
Resistor and marking withstand all accepted industrial
cleaning fluids.
